Sustainability: a Dissent

Abstract:  Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchot-era conservation (and thus ignores the many lessons learned since then); it need not be linked to land, to the land's functioning, or to any ecological science; it need not include a moral component; it is consistent with the view of humans as all-powerful manipulators of the planet; and, in general, it is such a malleable term that its popularity provides only a facade of consensus. When sustainability is defined broadly to include the full range of economic and social aspirations, it poses the particular risk that ecological and biodiversity concerns will be cast aside in favor of more pressing human wants. Given these many defects, the conservation movement should discard the term in favor of a more alluring goal, attentive to nature and its ecological functioning. A sound goal would incorporate and distill the considerable ecological and moral wisdom accumulated since Pinchot's day while giving conservationists the rhetorical tools needed to defend the land against competing pressures. In our view, conservation would be well served by an updated variant of "land health," Aldo Leopold's ecologically grounded goal from the 1940s. Land health as an independent understanding should set the essential terms of how we live and enjoy the earth, providing the framework within which we pursue our many social and economic aims.

Motivated to disengage: The ethical consequences of goal commitment and moral disengagement in goal setting

A growing literature has suggested that high performance goals can have unintended consequences within organizations as employees engage in unethical behavior to achieve outcomes associated with goal attainment. Extending research on the dark side of goal setting, we suggest that high performance goals not only create a desire to achieve a particular outcome but also alter moral reasoning processes related to goal attainment. Integrating goal-setting theory with motivated moral reasoning, we hypothesize an indirect effect of high performance goals on unethical behavior via state moral disengagement. We also examine goal commitment—which tends to amplify the relationship between high goals and performance—as a key boundary condition associated with this indirect effect. We build this conditional indirect effect model across three studies conducted in the field and the laboratory. Our results provide new insight into both when and why high goals can facilitate moral disengagement and unethical behavior within organizations.     

Quantitative method to determine the regional drinking water odorant regulation goals based on odor sensitivity distribution：Illustrated using 2-MIB

Taste and odor （T/O） in drinking water often cause consumer complaints and are thus regulated in many countries. However, people in different regions may exhibit different sensitivities toward WO. This study proposed a method to determine the regional drinking water odorant regulation goals （ORGs） based on the odor sensitivity distribution of the local population. The distribution of odor sensitivity to 2-methylisobomeol （2-MIB） by the local population in Beijing, China was revealed by using a normal distribution function/model to describe the odor complaint response to a 2-MIB episode in 2005, and a 2-MIB concentration of 12.9 ng/L and FPA （flavor profile analysis） intensity of 2.5 was found to be the critical point to cause odor complaints. Thus the Beijing ORG for 2-MIB was determined to be 12.9 ng/L. Based on the assumption that the local FPA panel can represent the local population in terms of sensitivity to odor, and that the critical FPA intensity causing odor complaints was 2.5, this study tried to determine the ORGs for seven other cities of China by performing FPA tests using an FPA panel from the corresponding city. ORG values between 12.9 and 31.6 ng/L were determined, showing that a unified ORG may not be suitable for drinking water odor regulations. This study presents a novel approach for setting drinking water odor regulations.

A MULTIOBJECTIVE MODEL FOR REGIONAL WATER QUALITY MANAGEMENT1

ABSTRACT: Linear programming is the simplest of all the optimization techniques used in regional water quality management studies; but the technique can optimize only one goal. When there are multiple goals with the same or different priorities, goal programming is a useful decisionmaking tool. This paper illustrates the application of goal programming to a regional water quality management problem where the following two goals are considered: (1) minimize the total cost of waste treatment, and (2) maintain the water quality goals (dissolved oxygen) close to the minimum level stated in the stream standards.     

仙女湖富营养化特征与水环境容量核算

以典型的亚热带大型水库——江西省仙女湖为例,于2011~2013年季节性监测了仙女湖水体理化指标。采用综合营养状态指数法对其富营养化状态进行了评价,并采用沃伦威德尔模型(Vollenweider)和狄龙模型(Dillon)计算了COD、NH₃-N、TN和TP的水环境容量。结果表明:仙女湖水质总体处于地表水Ⅱ类~Ⅲ类标准,TN 0.32~0.91 mg/L、平均0.59 mg/L,NH₃-N 0.012~0.59 mg/L、平均0.31 mg/L,TP 0.017~0.080 mg/L、平均0.028 mg/L,COD_Mn 1.61~5.59 mg/L、平均2.85 mg/L,Chl-a 0.37~0.95 μg/L、平均0.56 μg/L。从湖区上游到下游,各指标尤其是总氮、总磷、透明度和氨氮呈现明显的趋优变化特征,除TP出现Ⅲ类水质外,其余指标多年持续处于Ⅱ类水质状态;从单因子状态指数来看,采用透明度评价的营养状态最高,大部分湖区持续处于轻度富营养状态;TN和TP评价的营养状态次之,处于中营养水平。仙女湖COD、NH₃-N、TN和TP水环境容量分别为21 208.0、3 528.8、4 991.2和248.1 t/a,分别剩余容量比率56.88%、68.25%、62.89%和13.67%,影响仙女湖水环境容量最突出的环境因子为TP。同时,基于对水环境容量影响因素的分析,最后提出了提高仙女湖区水环境容量的建设性方案。

You think you are big fish in a small pond? Perceived overqualification,goal orientations,and proactivity at work

Overqualification denotes situations in which job incumbents have higher qualifications than those required for the job. Drawing on the self‐regulatory perspective, we proposed that employees' perception of overqualification positively affects their proactive behavior through the mechanism of role‐breadth self‐efficacy and that this indirect effect is moderated by employees' goal orientations. We tested our hypotheses through two studies. In Study 1, we found that perceived overqualification had a positive indirect effect on employees' proactive behavior through role‐breadth self‐efficacy using a sample of 323 salespeople with a cross‐lagged panel design. In Study 2, the multi‐wave and multi‐source data from 302 teachers confirmed the indirect effect and indicated that performance goal orientation and learning goal orientation moderated the indirect relationship.
